A vacuum flange is a flange at the end of a tube used to connect vacuum chambers, tubing and vacuum pumps to each other. Vacuum flanges are used for scientific and industrial applications to allow various pieces of equipment to interact via physical connections and for vacuum maintenance, monitoring, and manipulation from outside a vacuum's chamber.
In reality, a wrench with a width across the flats of exactly 15 mm would fit too tightly to use on a bolt with a width across the flats of 15 mm. The tolerances necessary to make the tools usable are listed in documents such as ASME/ANSI B18.2.2 for U.S. standards. [1]
A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an Steel beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its ...
NPT is defined by ANSI/ASME standard B1.20.1. [4] The taper rate for all NPT threads is 1 inch of diameter in 16 inches of length (3 ⁄ 4 inch per foot or 62.5 millimeters per meter) measured by the change of diameter (of the pipe thread) over distance of thread.
The American Welding Society (AWS) publishes over 240 AWS-developed codes, recommended practices and guides which are written in accordance with American National Standards Institute (ANSI) practices. [1] The following is a partial list of the more common publications: [citation needed]
ANSI B5.18-1972 specifies some essential dimensions for milling machine spindles and tool shanks using taper sizes 30, 40, 45, 50, 60. [13] The specifications describe the position of the driving key and flange and the thread of the drawbar bolt that holds the shank in the spindle.
